ABSTRACT
With the rapid development of the transportation industry, the demand for real-time positioning and tracking of vehicles has become increasingly urgent. Traditional vehicle positioning methods rely on manual recording or simple navigation devices, which have problems such as low positioning accuracy, delayed information update, and inability to monitor vehicle speed in real-time, making it difficult to meet the safety and efficiency requirements of vehicle management.
The vehicle positioning and tracking system based on the STM32F103C8T6 microcontroller integrates a GPS positioning module, DS1302 clock module, KY-003 Hall detection module, 3 independent buttons, and an OLED display, realizing real-time vehicle positioning, time synchronization, vehicle speed detection, and information display functions. The core functions of the system include: obtaining real-time vehicle position information (latitude and longitude) through the GPS module; acquiring the current time with the DS1302 clock module, supporting time correction via buttons; monitoring the vehicle’s driving speed in real-time using the KY-003 Hall detection module; synchronously displaying positioning information, time, and vehicle speed through the OLED display; and completing operations such as time correction and vehicle speed adjustment via 3 independent buttons.
The implementation of this system effectively improves the real-time performance and accuracy of vehicle positioning and tracking, meets the demand for comprehensive monitoring of vehicle driving status, provides reliable data support for vehicle management and safety dispatching, and also offers a reference for the research and development of similar vehicle positioning equipment, with high practical application value.
